Continuation of U.S. Appln. No. 09/41 1,256
APPENDIX
VERSION WITH MARKINGS TO SHOW CHANGES MADE
IN THE CLAIMS ;
The claims are amended as follows:
1 . (Once amended) A load handling apparatus for a counterbalance type forklift,
comprising:
one tillable operating lever disposed on a body of the forklift;
a mast tiltable in an anteroposterior direction and disposed on said forklift;
a Uftable fork disposed on said mast;
a solenoid proportional control valve, in which a tilting speed of said mast and lifting and
lowering speeds of said fork are controlled by a degree of opening of said solenoid proportional
control valve, said degree of opening being proportional to a tilting angle of said operating lever;
a switch attached to said operating lever; and
a controller [for controlling so as to output a signal for tilting] that tilts said mast when
said operating [level] lever is tilted and [under a state where] said switch is in a first switching
state [operated], that [output a signal for lifting or lowering] lifts or lowers said fork when [only]
said operating lever is [operated; and disable actions of lifting and lowering] tilted and said
switch is in a second switching state, and that prevents lifting and lowering of said fork when
said switch is changed from said first switching state to said second switching state [to an
inactive condition under a state where] while said operating lever is tilted [in an tilting operation
condition unless said operating lever is returned to a neutral condition].
